To all whom it may concem:

Be it known that I, SmkaNosUKn U'rsUNo- Mira, a subject of the Emperorof Japan, residing at Vancouver, in the Province of British Columbia andDominion of Canada, have invented new and useful Improvements inEducational Devices, of which the following is a speciication.

This invention relates toeducational devices, particularly designed forthe instruction of gcography, the main obpect of the invention being toprovide an educational globe which may be adjusted to diferentobservation angles and rotated freely on its axis for the purpose ofbringing the different portions thereof clearly into view.

A further' object of the invention is to provide an education globewhich is adapted to be pneumatically intlated, and which, with thesupporting elements thereof, may be collapsed and packed in closecompass for storage or transportation.

The invention consists of the features of construction, combination andarrangement of parts herein fully described and claimed, reference beinhad to the accompanying drawings in w ich Figure 1 is a Perspective viewshowing the globe mounted for use. Figs. 2 and 3 are enlarged detallsections on the lines 2-2 and 3-3 of Fig. 1. Fig. 4: is a detail viewvof the folded bracket. Fig. 5 is a similar view of the supporting stand.

In earrying my invention into practrce, I provide an educational devicecomprismg generally a globe 1, supporting bracket 2 and supporting stand3.

The lobe 1 comprises an inner inflatable sac a 4 of rubber or othersuitable elastic material capable of holding air, and an outerproteetive suck or casing 5 therefor, which may be made of cloth orother suitable material and upon the outer surface of which is paintedor otherwise produced an ordinary pictorial representation of the globe.The sacks f are capable of expanding fully under a determined airressure, and of collapsing when relieved o the air pressure to permitthem to be rolled or folded in compact form. In line with the poles andaxis of the globe filling and discharfle tubes or nipples G and 7 areprovide which nipples are secured in any substantial manner to bothsacke and communicate with the interior of the inner sack. The nipple 6is provided With a checkvalved fitting 8 for connection with an air pumpof any suitable type, by which the globe may be inllated, said nipplebeing otherwise closed, while the nippie 7 is adapted to form a ventpassage and is normally closed by a plug 9, upon the removal of whichthe contained air may be rapidly exhausted from the globe for itscollupse.

The globe may be made of any preferred size or capacity of ex anding toany given diameter, and prefera ly the outer sack is provided With asuitable bendable portion (not shown) sewed or otherwise fastened inclosed position so as to permit of the ready insertion and removal ofthe inner sack, in order that the sacks may be eonveniently assembledand repairs to the inner sack readily made, the nipples (5 and 7 beingso connected with the inner sack as to permit of these Operations.

The bracket 2 is of segmental form to surround one-half of the globe,and consists of a series of sections 10, 1l and 12, adapted to becoupled and held rigidly in proper relationship for use by suitablefastening devices 13. As shown, the said sections of the bracket arehingedly connected, as at 14, so that, upon the disengagement of thefastening elements, they may be folded com actly in parallel relation,as illustrated in lig. 4. The outer ends of the bracket sections 10 and1'2 are notched, as at 15, to receive and engage rings or the like onpivot members 16 carried b the ni ples 6 and 7, whereby the globe isetachab y connected with the rack and is adapted to revolve thereon inthe plane of its axis. Each nipple is provided with an annular series ofrack teeth 17 adapted to be engagcd by a dog 18 consisting of a lengthof s ring wire pivoted to the adjacent end of the bracket. This dog maybe folded parallel with the adjacent portion of the bracket to allow theglobc to have free revoluble movement, and either or both dogs may bemoved into cngagement with the coacting rack teeth to limit the speed ofrotation of the globe or lock it in fixed or set position for thedisplay of any particular portion of its surface.

The bottom section 10 of the rack is provided with a lug or projection19 to which is pivoted, as at 20, a rod or tube 21, which is adapted totelescopically en a e a tubular standard 22, forming) part o t e stand3, teeth or notchcs 23 emg provided on the member 21 to interlock wlth adog 24 on the standard, whereby said parts may be held rigidly and yetdetaehably connected. The bracket and globe are adapted to swing uponthe pivot 20 in a forward and rearward direction so that the globe maybe adjusted to different angles for more convenient observation ascircamstances or occasion may require. The bracket and globe are adaptedto be fastened at the desred angle of inelination by a toothed racksegment 25 pivoted to the bracket section 10 and movable through andengageable with a guide loop and locking member on the depending rod ortube 21.

'l`he tubular standard :22 of the supporting stand carries at its lowerend a series of pivoted legs "27 having weighted feet 28, \vhich legsare arranged equidistantly around the standard and are adapted. to bespread out- \vard to firmly support the device upon a floor, table orother surface. The legs are adapted to be folded inwardly or collapsed,as shown in Fig. 5, and are connected by bracing or stay links '29 witha runner 30 slidable on the standard 22, whereby the braces are adaptedto permit inward and outward movements of the legs, the runner 30carrying a pivoted dog or looking device 31 adapted to engage a fixedshoulder 32 on the standard to lock the lefl's in outspread conditionand prevent accidental collapse thereof.

In Setting up the device for use,-the parts of the stand and bracket maybe extended and assembled in an obvious manner, and the globe theninflated and mounted in position by slipping the enga ing rings of thepivot 16 over the notche ends 15 of the bracket` The globe thus mountedfor use may be revolved on its axis and adjusted to dill'erent anglesfor convenience in instructing large or small classes in geography. Whenit is desired to disassemble the device and pack or storo the same awayin close compass, the lebe may be detaehcd from the bracket anildefiated and the arts of the bracket and stand folded, as wil be readilyunderstoodfwhereupon all of the elements of the device may be inclosedwithin a suitable rece Jtacle.

The a vantages of the invention will be evident from the foregoingdescription, and it will be understood that, while the invention isprimarily designed for use in instructing Students in geography, it maybe employed for any other purposes for \vhich the device is adapted.

I claimz- 1. In an educational device, a collapsible pneumatic globe, asupport therefor, and members detaehably and rotatably connecting theglobe \vith said support, part of said members serving as filling anddischarge devices.

2. In an educational device, a stand, a bracket pivotally mounted uponthe stand, a collapsible globe provided with inlet and dischargenipples, means connected with the nipples for detaehably and rotatablymounting the globe upon the bracket, means for controlling the tltingmotion of the bracket upon the stand, and means for looking the globe atany point against rotation.

3. In an educational device, a eollapsible, vertically adjustable stand,a foldable bracket pivotally mounted upon the stand, a collapsible globeprovided with inlet and discharge nipples, means connected \vith thenipples for detaehably and rotatably mounting the globe upon thebracket, means for controllin the tilting motion of the bracket upon tie stand, and means for locking the globe at any point against rotation.

4. In an educational device, a stand, a bracket pivotally mounted uponthe stand, a collapsible globe provided with inlet and dischargenipples, means connected with the nipples for detaehably and rotatablymounting the globe upon the bracket, and means for controlling thetilting motion of the bracket upon the stand.

5. In an educational device, a collapsible globe, a sup orting brackettherefor composed of fold able sections, a foldable stand to which thebracket is pivotally conneeted for the control adjustment, and meansdetaehably and rotatably mounting the collapsible globe upon thebracket, said means serving as air inlet and discharge devices.

In testimony \vhereof I ailix my signature in presence of two witnesses.
